can you extract the tab-open logic in App.tsx into a custom hook?
Sure — I'll pull the tab state and the openTab/closeTab handlers out of App.tsx into a useTabs hook so the shell layout stays declarative.

looks good, also add a pinTab function
Done — added pinTab(id) that converts a preview tab to persistent. I've also updated TabBar to call it on double-click.
